Airworthiness Directives; B-N Group Ltd. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for B-N 
Group Ltd. Models BN-2, BN-2A, BN-2A-2, BN-2A-3, BN-2A-6, BN-2A-8, BN-
2A-9, BN-2A-20, BN-2A-21, BN-2A-26, BN-2A-27, BN-2B-20, BN-2B-21, BN-
2B-26, BN-2B-27, BN2A MK. III, BN2A MK. III-2, and BN2A MK. III-3 
airplanes. This AD results from mandatory continuing airworthiness 
information (MCAI) issued by an aviation authority of another country 
to identify and correct an unsafe condition on an aviation product. The 
MCAI describes the unsafe condition as damage of the cable sliding end 
assembly and installation of the incorrect end fitting on engine 
control cable assemblies. We are issuing this proposed AD to require 
actions to address the unsafe condition on these products.

DATES: This AD is effective April 1, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of April 1, 
2014.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to B-N Group Ltd. Models BN-2, 
BN-2A, BN-2A-2, BN-2A-3, BN-2A-6, BN-2A-8, BN-2A-9, BN-2A-20, BN-2A-21, 
BN-2A-26, BN-2A-27, BN-2B-20, BN-2B-21, BN-2B-26, BN-2B-27, BN2A MK. 
III, BN2A MK. III-2, and BN2A MK. III-3 airplanes. That NPRM was 
published in the Federal Register on October 30, 2013 (78 FR 64894). 
That NPRM proposed to correct an unsafe condition for the specified 
products. The MCAI states:

    Britten-Norman Aircraft Limited has been made aware of two 
occurrences where a failure of engine control cable assemblies has 
caused engine control difficulties. In both reported cases, the 
cable sliding end assemblies were in poor condition and in both 
cases, an incorrect end-fitting was installed which may have 
contributed to the failures.
    This condition, if not detected and corrected, could result in 
reduced engine control, possibly resulting in reduced control of the 
aeroplane.
    To address this potential unsafe condition, Britten-Norman 
Aircraft have issued Service Bulletin (SB) 334 to provide inspection 
instructions.
    For the reason described above, this AD requires a one-time 
inspection and functional test of the engine control cables and, 
depending on findings, replacement of the cables.

    The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2013-0924-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 64894, October 30, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 64894, October 30, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 64894, October 30, 2013).

Costs of Compliance

    We estimate that this AD will affect 101 products of U.S. registry. 
We also estimate that it will take about 1 work-hour per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $8,585, or $85 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 10 work-hours and require parts costing $4,800 (4 per 
airplane), for a cost of $5,650 per product. We have no way of 
determining the number of products that may need these actions.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

    You may examine the AD docket on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-
2013-0924; or in person at the Docket Management Facility between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains the NPRM, the regulatory evaluation, any comments 
received, and other information. The street address for the Docket 
Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments 
will be available in the AD docket shortly after receipt.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as damage of the 
cable sliding end assembly and installation of the incorrect end 
fitting on engine control cable assemblies. We are issuing this AD 
to detect and correct damage of the cable sliding end assembly 
(cracking, distortion, corrosion) and incorrect end fittings on the 
engine control assemblies, which could lead to reduced engine 
control with consequent loss of control.

(f) Actions and Compliance

    Unless already done, do the following actions in paragraphs 
(f)(1) through (f)(4) of this AD:
    (1) Within the next 6 months after April 1, 2014 (the effective 
date of this AD), do a one-time inspection of the engine control 
cable assemblies, part number (P/N) 137835, P/N 172449-1, P/N 17250, 
and P/N 172451, and surrounding areas for damage (cracking, 
distortion, corrosion) and correct cable end-fitting and to assure 
the wire locking is intact following Britten-Norman Aircraft Limited 
Service Bulletin No. SB 334, Issue 1, dated August 30, 2013.
    (2) If no discrepancies are found during the inspection required 
in paragraph (f)(1) of this AD, inspect the control linkages for 
proper adjustment and, before further flight, make any necessary 
changes following Britten-Norman Aircraft Limited Service Bulletin 
No. SB 334, Issue 1, dated August 30, 2013.
    (3) If any discrepancies are found during the inspection 
required in paragraph (f)(1) of this AD and/or the control linkages 
cannot be properly adjusted as specified in paragraph (f)(2) of this 
AD, before further flight, replace the engine control cable assembly 
with a serviceable unit following Britten-Norman Aircraft Limited 
Service Bulletin No. SB 334, Issue 1, dated August 30, 2013.
    (4) After April 1, 2014 (the effective date of this AD), do not 
install on any airplane engine control cable assemblies, part number 
(P/N) 137835, P/N 172449-1, P/N 17250, and P/N 172451, unless they 
are new or have been inspected as required in paragraphs (f)(1) and 
(f)(2) of this AD and found free of any discrepancies and have 
proper adjustment.
